WINDOW-SHADE HANGER.

Specicaton of Letters Patent.

Patented July 22,1913.

Application filed April 9, 1912. Serial No. 689,600.

To @ZZ whom/@'15 may concern Be 'it known that I, JOSEPH PETRITSGH, acitizen of the United Sta-tes, residing at Chicago Heights, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Vindow- Shade Hangers, of which the following isa specification.

The present invention relates to improvements in window shade hangers ofthe adjustable type, and it has for its object to provide a hanger ofthis character which may be readily moved to different points along awindow frame in order to position the shade carried thereby at varyingheights, thus adapting the shade to exclude the rays o-f the sun withoutcutting off the light, and thereby permitting the room to be ventilatedat the same time that the heavy light is excluded.

A further ob-ject of the present invention is the provision of a shadehanger the construction of which is such that it may be balanced indifferent positions of adjustment, thus precluding the necessity forcumbersome attachment fixtures to be applied to the window casing.

Furthermore, the invention also has in contemplation the provision of awindow shade hanger which is capable not only of adjustment verticallyof the window, but also laterally thereof, whereby to adapt the hangerfor different widths of windows.

With these general objects in view, and others which will appear as thenature of the improvements is better understood, the invention consistssubstantially in the novel construction, combination and arrangement ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and pointed out in the appended claims.

In the drawings: Figure l is a side elevation of a window shade hangerconstructed in accordance with the present invention, and illustrated inapplied position to Ia window. Fig. 2 is a transverse sectional view onthe line 2-2, Fig. l. Fig. 3 is a vertical transverse sectional view ofthe ad j ustable counterweight which forms a part of the hanger.

Referring in detail to the accompanying drawings, the numeral 10designates a tubular supporting bar, the same being formed of a bodysection 11, and telescopic terminal sections 12. The body section 1l isrectangular in cross section, while the terminal sections l2 partake ofan inverted U- shaped cross section. Because of the telescopic relationof the terminal sections 12 with the body section 11, it will beapparent that said sections 12 may be adjusted at different points alongthe length of the body section 11, the latter being provided withterminal slots 13 which receive adjusting screws let, said screws beingcarried by the terminal sections 12 and serving to hold the sections l2at their different points of adjustment. At the outer ends of thesections l2 are depending hanger arms l5, said arms being of appropriateconstruction to properly support a window shade, designated as 16, andwhen so supported, it will be obvious that the shade 16 may be operatedin the usual way.

Journaled in each of the terminal sections l2 is a pulley 17, and thebody section 1l is provided with similar pulleys 18, journaled at pointsadjacent to the center of the body section, and over the pulleys 17 and18 is passed a suspending cable 19, which is preferably in the form of acord. The extremities of the cable 19 are suitably con- Vnected tosuspending devices 2O applied to the window casing, and arranged at thecentral portion of the latter is a pair of supporting pulleys 2l whichare journaled in a housing 22. The cable 19 is looped about the pulleys2l and extends from the latter downwardly in parallel strands, saidstrands passing through a counterweight 23. The counterweight 23includes a casing 24, the lower end of which is closed, and applied tothe upper end of said casing 24k is a cap 25 to permit access to be hadto the interimL of said casing, the cap 25 being fitted to an annularflange 26, and seating upon a shoulder 27 which surrounds the base ofsaid flange. rIhe casing 24 and its cap 25 may be formed of any suitablematerial, but preferably soft rubber.

The parallel strands o-f the cable 19 pass through suitable perforationsin the cap 25 and the lower end of the casing 24, and through the boreof an adjusting device 28. This device is preferably in the form of arubber ball, and by reason of the elasticity thereof the sametenaciously adheres to the lower ends of the strands of the cable, so

thatl the ball is held upon the cable at any point of adjustmentthereon. By reason of this the counterweight 23 will follow theadjustment of the adjusting device 28. That the counterweight may beadapted to shades of different weights the interior 'of the casing 24 isprovided with a filling capable of variation in weight in accordancewith the conditions of use of the counterweight. This is accomplished byplacing within the casing 24 a plurality of shot 29, butl any means maybe provided for this purpose which will be effectual in weighting thecasing 24 in varying degrees.

In the use of the hereindescribed hanger, the same is suspended asillustrated in Fig. 1, wherein the extremities of the cable 19 areillustrated as connected to the supporting vdevices 20, and passingaround the pulleys 17, 18 and 21. The casing 2li is filled to thedesired extent with the shot 29, and the curtain is applied to thehanger arms 15. It will be understood, of course, that the terminalsections 12 oi' the supporting bar are adjusted along the body section11 Ain accordance with the width of the shade,

the screws 14 holding the respective sections of the supporting bar inthe adjusted position. Inasmuch as the counterweight 23 sustains theshade in the position to which it is moved, it is evident that the shademay be operated to screen 'the window to the desired extent withoutvarying the position of the supporting bar 10. By properly adjusting"the height of the counterweight 23 the supporting bar 10 may bc raisedor lowered, and thus the space above the supporting bar may also bevaried to admit vor exclude the light thereabove, as well as toventilate through the upper portion of the window, when this may bedesired.

The shot 29 may be supplied to or removed from the casing 24 by removingthe cap 25, and, as previously indicated, the adjusting device 28 mayalso be moved along the par- Copies of this patent may be obtained forve cents each, by addressing the Commissioner of Patents,l

allel strands of the cable 19 without affecting the friotio-nal gripthereof on the cable.

I claim:

1. In a window shade hanger, a bar proportioned to extend transverselyof a window frame and provided with a plurality of rollers, rollerssecured to the top of the window frame and` in alinement with thecentral rollers of the bar, and a. cable secured to the top of thewindow frame adjacent its ends and passing about the rollers of the barand the rollers at the top of the frame and extending downwardly beyondthe bar.

2. In a window shade hanger, a bar constructed in adjustable sections,rollers spaced apart and journaled adjacent the center of the centralsection, rollers journaled adjacentI the ends of the extreme section,rollers journaled adjacent the center of the top of the window frame,and cables having their extremities secured adjacent the ends of the topof the window frame and passing about the rollers of the bar and overthe rollers carried by the window frame and terminating in a hand-ho-ldbelow the bar.

3. In a window shade hanger, a section having rollers journaled adjacentits middle, bar sections telescopically connected with both ends of thefirst mentioned bar section and extending beyond the ends thereof,rollers journaled adjacent the ends of the telescopic sections, rollersjournaled adjacent the middle of the top of the window frame, cableshaving their extremities se-V cured adjacent the ends of the top of thewindow frame and passing about the rollers of the bar and upwardly overthe rollers of the window frame and downwardly beyond the bar andterminating in a handhold.

In testimony whereof I atlix my signature in presence of two witnesses.
